What Do the Piano Footpedals Do? A Comprehensive Guide


The piano is one of the most popular musical instruments in the world. It has been around for centuries, and its popularity has only grown. One of the most important features of the piano is its foot pedals. These pedals are located at the instrument’s base and are used to create different effects in the sound produced by the piano.

There are usually three pedals on a piano. From left to right, they are: they are the soft pedal, the sostenuto pedal, and the sustain pedal. Each pedal has a unique function that affects the sound of the piano differently. The sustain pedal, for example, is the most commonly used, and it is used to create a fuller, richer sound by allowing the strings to vibrate freely.

Understanding how the foot pedals work is essential for anyone who wants to play the piano. Whether you are a beginner or an experienced pianist, knowing how to use these pedals can help you create a more expressive and nuanced sound. In this article, we will explore the different types of piano foot pedals and their functions so that you can better understand how to use them effectively in your playing.

What Do the Piano Footpedals Do? A Comprehensive Guide

What are Piano Foot pedals?

Piano foot pedals are an essential part of the piano that allows the player to alter the sound produced by the instrument. These pedals are located at the piano’s base and operated by the pianist’s feet. A piano typically has three pedals, although some models may have fewer or more.

Types of Piano Footpedals

There are three main types of piano foot pedals:

  • Sustain Pedal: The sustain pedal is the most commonly used piano pedal. When the pianist presses down on this pedal, it raises the dampers from the strings, allowing them to vibrate freely. This creates a sustained sound that can be held for as long as the pedal is depressed.
  • Soft Pedal: The soft pedal is the una corda pedal. When the pianist presses down on this pedal, it shifts the entire keyboard to the right, forcing the hammers to hit only one (or two) strings per note instead of the usual three. This creates a softer, muted sound.
  • Sostenuto Pedal: This is less common than the sustain and soft pedals. When the pianist presses down on this pedal, it sustains only the notes being played. This allows the pianist to create a sustained sound while still being able to play other notes without sustaining them.

Each pedal serves a unique purpose and can create a wide range of sounds on the piano. Understanding how they work and when to use them is essential for any pianist looking to master the instrument.

Sustain Pedal

The sustain pedal, or damper pedal, is one of three foot pedals found on pianos. It is located to the right of the other two pedals and is played with the right foot. When pressed, the sustain pedal lifts all the dampers off the strings, allowing the notes to continue to ring even after the pianist has lifted their fingers off the keys. This creates a sustained, full-bodied sound often used in many different styles of music.

How the Sustain Pedal Works

When a key on the piano is pressed, a hammer strikes a string, causing it to vibrate and produce a sound. When the key is released, a felt damper falls onto the string, stopping the sound. The sustain pedal lifts all the dampers off the strings simultaneously, allowing the strings to vibrate freely and continue producing sound. This creates a rich, full sound that can be sustained if the pedal is held down.

On a grand piano, the sustain pedal is usually the rightmost pedal, operated by the right foot. On an upright piano, the sustain pedal is located to the right of the other two pedals and played with the right foot. Some pianos also have a middle pedal, used for various purposes, including sustaining specific notes or creating a muted sound.

Uses of the Sustain Pedal

The sustain pedal is used in a variety of ways by pianists. It can create a legato effect, where notes are played smoothly and connected. It can also create a more resonant sound by allowing the strings to vibrate and produce sympathetic resonance with other strings. This effect is particularly noticeable on grand pianos, where the strings are longer and can produce a more complex sound.

The sustain pedal is also used in many different styles of music, including classical, jazz, and pop. In classical music, the pedal is often used to create a sustained sound reminiscent of the music of Mozart and other classical composers. The pedal is often used in jazz and pop music to create a more lush, full-bodied sound characteristic of those genres.

Overall, the sustain pedal is an essential tool for any pianist, allowing them to create various sounds and effects on the piano. Whether playing on an acoustic or digital piano, the sustain pedal is an important part of the piano mechanism that allows pianists to express themselves and create beautiful music.

Soft Pedal

The soft pedal, or the una corda pedal, is one of the three foot pedals found on most pianos. When pressed, the soft pedal slightly shifts the entire piano action to the right, causing the hammers to strike only one or two strings per note instead of the usual three. This results in a softer and additionally muted sound.

How the Soft Pedal Works

When the soft pedal is pressed, it causes the una corda mechanism moves the entire piano action to the right. This movement causes the hammers to strike only one or two strings per note instead of the usual three. The una corda mechanism works by shifting the position of the keyboard and action assembly slightly to the right so that the hammers strike fewer strings.

Uses of the Soft Pedal

The soft pedal is most commonly used to create a softer and hushed piano sound. It is especially useful in playing slow and quiet pieces where a full sound might be overwhelming. The soft pedal can also create a more subtle and delicate sound, such as playing arpeggios or chords.

Another use of the soft pedal is to practice quietly without disturbing others. Using the soft pedal significantly reduces the sound of the piano, making it easier to practice without disturbing others in the same room or nearby.

It is important to note that the soft pedal does not change the timbre or quality of the sound produced by the piano. Rather, it simply reduces the volume and intensity of the sound.

Sostenuto Pedal

How the Sostenuto Pedal Works

The sostenuto pedal, or “sost,” is the middle pedal on a grand piano. When the player depresses the Sostenuto pedal, it sustains only the notes being held down. This means that the player can hold down a note or chord with the right pedal (damper pedal) and then press the sostenuto pedal to sustain only those notes while the player’s hands are free to play other notes without sustaining them.

The sostenuto pedal works by holding up the dampers of the selected notes, allowing them to vibrate freely while the other strings are damped. This is done by separating the Sostenuto pedal from the other two. When pressed, the pedal lifts a rod that activates the sostenuto mechanism, which holds the dampers up for the selected notes.

Uses of the Sostenuto Pedal

The sostenuto pedal is not used as frequently as the other two pedals on a piano, but it can be useful in certain situations. One common use of the sostenuto pedal is in music, requiring the pianist to sustain particular notes while striking other keys without sustaining them. This is particularly useful in music with multiple voices or melodies that must be heard distinctly.

Another use of the sostenuto pedal is in music that requires a specific effect, such as a bell-like sound. Using the Sostenuto pedal, the pianist can sustain individual notes while playing others, creating a unique sound that cannot be achieved with the other two pedals.

A sostenuto pedal is useful for pianists who want to create specific effects or sustain specific notes while playing others. While it is not used as frequently as the other two pedals on a piano, it can be valuable to a pianist’s toolkit.

A Last Words on Piano Foot Pedals

Understanding the different functions of the piano foot pedals is crucial for any pianist who wants to convey emotions and dynamics in their music effectively. The soft pedal reduces the volume and changes the tone of the notes, while the sostenuto pedal sustains specific notes without affecting others. On the other hand, the sustain pedal allows all notes to sustain and blend, creating a fuller sound.

Knowing when and how to use each pedal can greatly enhance a pianist’s performance and interpretation of a piece. It is important to note that not all pianos are created equal, and the pedals may have different effects depending on the instrument. Therefore, it is recommended to experiment with the pedals on different pianos to understand their capabilities fully.

Overall, the piano foot pedals are essential for any pianist looking to add depth and nuance to their playing. With practice and experimentation, pianists can master the use of the pedals and take their performances to the next level.
